How to install this?

Install this firmware like any other official firmware update from Sony.

If you are currently using a modified firmware version, you will first need to revert back to the stock firmware (please refer to the instructions for the installed firmware).

Connect the player to the PC via the USB cable, enable the Mass Storage mode, and then execute the installer.


How to uninstall this?

If you wish to return to the stock 1.10 official firmware for A40, just go on and install it. That's it.

    1. Hey, this works like any other stock firmware, so you don't have to do something in particular if you want to install A40 FEv2 afterwards.

    2. Hi...I have the WM1Z and tuning installed on my A45. Can I install this MRW 08.02 this over top to get my Radio back or do I have to revert everything back to stock and just install the A50 firmware for A45.....I'm in Canada

      Thanks

      Thanks

  3. Try disabling the Battery Care option, then discharging the battery completely, and then letting it completely charge without using the player. This should help with the calibration of the battery's capacity.

  4. I mentioned turning Battery Care off only before fully recharging the battery for the recalibration.

    I don't know what to say about this. Of course it also depends what types of files you are playing like MP3 vs FLAC, or if you're using DSP settings or not, but other than that I have no idea.

    1. Make sure that you don't see anything like "DMP-A40" in your Unit Information menu.

      If you see that, then please kindly revert back to the stock firmware, and then choose your firmware from here: https://www.mrwalkman.ml/a40series

      Please read all the info on the page of your chosen firmware, and then install it.

      All firmware available at the link above (https://www.mrwalkman.ml/a40series) will have the FM Radio function, except if the region of your player is CEW, which you can change with this tool: https://www.rockbox.org/wiki/SonyNWDestTool

  14. I got the jpn NW-A45 and installed the unofficial firmware to make it like the NW-A55 series. My unit is still in JPN language so not sure where to go to change language to English?

  15. Thank you so much MrWalkman. You saved me going mad. Bought the A45 but cover arts wouldnt work. I tried the Walkman One firmware, which fixed the artworks but i dont know why i preferred the ClearAudio+ and was nice to have the radio. Using this A50 version is perfect for what i wanted. Just sent you £10, thanks so much once again
